01 / START
Measure your
vent frame.
Use your phone camera.
No app or reference object needed.
Camera and motion access required
For vent types this test does not support, use a tape measure.
We measure the outside frame.
Include the entire border, not just the opening.
For rectangular wall vents within easy reach. Start with a frame nearly flush with a flat wall. Raised frames, recessed vents and overhead vents need another measurement method.
Test version. Estimates are not verified measurements. Check with a tape before ordering or cutting.
- 1 Scale
- 2 Wall
- 3 Capture
Allow camera & motion access
The scanner runs on your phone.
Your scan stays open. No need to start over.
Center one complete vent. Move closer safely until the frame fills most of the guide. Keep a little wall visible around all four outside edges.
Move slowly forward and back to find scale, then a little sideways to locate the surface. Avoid glare and keep the frame in view.
Use the photo measurement tool ↗This needs a live camera scan. A saved photo alone cannot establish scale.
03 / CHECK CORNERS
Check the outside frame.
Drag a point only if it needs adjusting.
Include the entire border, not just the opening.
Which vent are you measuring?
Choose the outline around your vent, then check its outside edges.
Fine-tune this corner
Tap a corner for a closer look. Arrow keys also work.
04 / RESULT
Your estimated
frame size.
Outside frame · Experimental estimate
Verify with a tape before ordering or cutting.
ADD TO YOUR LOG
Use a higher quantity only for vents you consider the same size.
Only measurements you add appear in your log.
Optional accuracy test
Enter tape measurements if you have them. They are not required to log a vent and do not change the estimate.
Adding or updating this entry also saves these test values.
Compare another scan of this vent
Choose an earlier scan of the same physical vent. Similar results show repeatability, not verified accuracy.
Compare the same outside edges. Check with a tape before ordering or cutting.
